摘要： A method of producing hydrogen cyanide by the gas-phase reaction of methane with ammonia at elevated temperature and an ammonia/methane ratio of 1.001 to 1.1. The conducting of the gaseous reaction mixture through a corona discharge causes the reaction to start at temperatures below 1000.degree. C. without the action of a catalyst. This results in considerable savings of the necessary investment expenses as well as of the running costs for energy.
